U.S. Energy Information Administration
Weekly US residential heating-fuel price intelligence from the U.S. Energy Information Administration's keyless hist_xls workbooks (No. 2 heating oil + propane, $/gal, national + five PADD regions, weekly since 1990, heating season Oct-Mar). Per fuel x region x week: retail price, year-over-year and 4-week change, heating-season flag. A retailer joins weekly revenue to week_date + region_code to model the heating-bill drag on discretionary spending; a subscription business reads propane/oil price spikes as churn-risk geography for the heating season; a sales team weights cold-climate territories by yoy_pct. Summer weeks are absent by design (survey pauses Apr-Sep), never interpolated. Source: U.S. Energy Information Administration (public domain).
US Natural-Gas Market Signals (derived)
Daily US natural-gas market signals from the EIA Henry Hub spot price (FRED DHHNGSP, 1997 ->, $/MMBtu): 90-day momentum, year-on-year change, 30-day change volatility, 3-sigma anomaly flags, naive-drift forecasts, price-spike day flags, an elevated-price ($5+) flag, a 5-year z-score, and a heating-season flag. The natural-gas companion to us-fuel-price-signals (pump prices) — gas moves on weather, storage, and LNG exports, with some of the sharpest spikes of any commodity. All rows normalized to country_code USA. Raw series: U.S. Energy Information Administration via FRED.
